Four-door version of new Audi super car debuts with race-developed V8 FSI power and new generation quattro.
An all-new V8-powered evolution of the widely acclaimed RS 4 quattro will dominate the Audi stand at the 2005 Geneva Motor Show (March 3-13), remarkable as much for its saloon body shell as for its awe-inspiring capabilities. The first ever B-segment Audi RS saloon epitomises Vorsprung durch Technik through numerous advances including an unprecedented combination of eight-cylinder power and FSI direct petrol injection and a new generation of quattro four-wheel-drive technology.
At the heart of the RS 4 quattro is a naturally aspirated 4.2-litre V8 FSI petrol engine that delivers 420PS, equating to a highly impressive specific output of just over 100PS per litre. Maximum torque of 430Nm occurs at 5,500rpm, and 90 per cent of this peak is available from 2,250rpm all the way to 7,600rpm, though the exceptionally free revving unit is actually capable of powering on well beyond this to 8,250rpm to provide breathtaking acceleration. The 0-62mph sprint is dispatched in just 4.8 seconds, 124mph from rest on a suitable Autobahn can be seen in only 16.6 seconds and an electronically limited top speed of 155mph is easily achievable.
FSI direct petrol injection, which cut its teeth in the V8-powered Audi R8 Le Mans racers before filtering into four and six-cylinder Audi road cars, appears for the first time in a road-going Audi V8, helping to maximise both performance and efficiency through even more effective and accurate fuel combustion.
